That's a good point, however, I view it as positive because at least they're saying to choose wisely and to commit to your marriage, whereas it is recognized that no harm comes from a homosexual relationship.

That doesn't fit with my understanding of both human nature and the scientific literature. Gottman's 4 Horseman don't suddenly appear many years after the couple is married. He can use this and a few other metrics to predict divorce to a very high degree-- above 90%.
